| Vetor | AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.4.12
Description
The issue is related to the incorrect use of the memory management system interface in the Linux kernel's scatterlist library. This can potentially allow an attacker to impact the integrity and availability of protected information. The
extract user to sg function in lib/scatterlist.c fails to unpin pages in a certain situation, which can lead to problems.Recommendations
For Linux kernel versions prior to 6.4.12, update to version 6.4.12 or later to resolve the issue. As a temporary workaround, consider restricting access to the
extract user to sg function in lib/scatterlist.c to minimize the risk of exploitation.Exploit
